Background: Older adults sometimes shy away from using modern digital communication devices due to lacking experience and fear of failure. Within the present project, SmartCards were developed as analogous means to operate tablet computers for older adults with little previous computer experience. We investigated whether the SmartCards-Tablet-System would (a) increase use of digital communication and (b) affect loneliness, autonomy, cognitive ability and wellbeing of the users. Methods: The suitability and acceptance of the system was evaluated during a three month trial period with seniors in retirement homes, seniors with home assistance care and a waiting control group. Results: Acceptance, duration of use and frequency of use were high in both experimental groups. Cognitive ability significantly improved after three months’ use in both experimental groups. Effects on loneliness, autonomy and wellbeing could not be observed. Discussion: Our results indicate that seniors are very much able and curious to use modern digital devices if the interface and hardware are adjusted to their needs and capabilities without being stigmatizing. The use of modern communication services and the World Wide Web can promote contact of seniors with their (younger) relatives.
